流體 ─ 一個洲際旅行方法的可行性
An old proposal for transcontinental travel along a fixed latitude is the following: Take a balloon high into the stratosphere. Wait until Earth has rotated the desired distance beneath you, then descend. Comment on the feasibility of this mode of transport.
There is a spelling mistake in your answer.
Not just one!
Please help me solve another question,would you?

Hint:Consider the Earth ratating speed, On Earth surface, the speed is supersonic.If the balloon travel to USA only by wind in one night,,then how fast would be that kind of wind on Earth surface? ...Can we live in that situation......? ^^WE ARE ALL LUCKY GUYS ^^
